Understanding Blue Fish: What Is It?
Blue fish, scientifically known as Pomatomus saltatrix, belongs to the family Carangidae. Commonly referred to as bluefish, these fish inhabit the Atlantic Ocean and are particularly prevalent along the U.S. East Coast and throughout the Mediterranean Sea. They are characterized by their sharp teeth, elongated bodies, and iconic bluish-green coloration on the top and silvery-white flanks.
Blue fish are recognized for their robust flavor, making them a popular choice among seafood enthusiasts. However, what sets blue fish apart is its unique fatty acid profile. To evaluate whether blue fish is an oily fish, it is essential to understand what constitutes oily fish.
What Defines Oily Fish?
Oily fish typically refer to species high in omega-3 fatty acids and have a higher fat content compared to white fish. The distinction generally is as follows:
- Oily Fish: Fish that contain 5% or more fat when raw.
